First we have 2 types of units of measurement so let’s make all the same type.
600mm= 60 cm
500mm= 50 cm
Tray dimensions are 60 by 50 cm and is a rectangle
Cake tin is round and has diameter 25 cm
We can fit 2 rows and 2 columns of tins
Since (25+25) is less or equal to 50
And (25+25) is less or equal to 60
Answer 4 cake tins
let the price of a slice of pizza be 'p' and that of soft drink be 's'
6 p + 5 s = 31.60............equation (i)
5 p + 4 s = 26.02............equation (ii)
6 p + 5 s = 31.60............×4
5 p + 4 s = 26.02............×5
24 p + 20 s = 126.4
25 p + 20 s = 130.1
p = 3.7
Answer = 3.7 Dollars
The correct answer is 75% increase.
The number 4 to 7 is increasing not decreasing since the number is higher than before.
Also 4 x 0.75 = 3 and 4 + 3 = 7 so it’s and increase of 75%
Hope this helps.
The answer is 10 + 30 = 40
20% = $180
100% = x
20x = 180 × 100
20x = 18,000
x = 900
The original price is $900
